Investigatory project chalk as shell of egg

Non-porous: Porosity in chalk could be as a result of the diatortion for the particle arrangement at drying when much water than necessary is used during moulding. Freeze drying. Definition of Terms : The researchers defined the following terminology based on how it is used in the investigatory project.

Ideally, a mixing process begins with the components, grouped together in some container, but still separate as pure components.

The relative importance of the mechanisms varies from one drying process to another and very often one mode of heat transfer predominates to such an extent that it governs the overall process.

Brittleness is a property of solid materials to break into pieces. The slurry is then placed into and extruded from a die—an orifice of the desired long, thin shape. Combine the crushed eggshells, hot water and flour in a bowl. The researchers conducted experiments to determine whether eggshells can be used as an ingredient in making homemade chalk rather than buying the commercialized product.

Gymnast — a person who practices gymnastics. Scope and Limitations The Study is only limited and focused on the investigation of Chicken Eggshells Gallus Domesticus used as an alternative source for chalk production.

On the surface of the outer membrane, mamillary knobs form as the first stage of shell formation, and from these, the main layer of the shell, called the palisade layer, develops. Clams — any of various bivalve mollusks, especially certain edible species.

The ensuing fine chalk is then washed, dried, packed in bags, and shipped to the manufacturer.
